Hydrostatic bearing and method of making same

Claim 1

THE METHOD OF FORMING A HYDROSTATIC BEARING ASSEMBLY ADAPTED FOR SUPPORTING A MOVABLE MEMBER FOR HIGHLY ACCURATE MOVEMENT WITH RESPECT TO A BEARING SURFACE OF A SUPPORT MEMBER, SAID ASSEMBLY INCLUDING A BEARING PAD ON ONE OF SAID MEMBERS HAVING A FLUID POCKET IN ONE FACE THEREOF WHICH IS PERIPHERALLY SURROUNDED BY A BEARING SURFACE JUXTAPOSED AND CLOSELY CONFORMING IN CONTOUR TO A BEARING SURFACE OF THE OTHER MEMBER, SAID METHOD COMPRISING THE STEPS OF FORMING A RECESS IN ONE OF SAID MEMBERS WHICH IS ADAPTED TO RECEIVE THE BEARING PAD WITH A RELATIVELY LOOSE FIT, INSERTING THE BEARING PAD WITHIN SAID RECESS AND ASSEMBLING THE MOVABLE MEMBER WITH THE SUPPORT MEMBER SO THAT THE BEARING SURFACE ON THE BEARING PAD IS ACCURATELY ALIGNED AND IN BEARING CONTACT WITH THE BEARING SURFACE ON SAID OTHER MEMBER, FILLING THE PORTION OF THE RECESS NOT OCCUPIED BY THE BEARING PAD WITH A RESINOUS MATERIAL WHICH WHEN SET IS ADAPTED TO RIGIDLY BOND THE BEARING PAD TO SAID ONE MEMBER AND LOCATE THE BEARING PAD IN RIGIDLY FIXED POSITION ON SAID ONE MEMBER IN ALIGNMENT AND BEARING CONTACT WITH THE BEARING SURFACE ON THE OTHER MEMBER, CAUSING SAID RESIN TO SET, AND THEREAFTER FORMING A CLEARANCE GAP OF UNIFORM WIDTH BETWEEN THE BEARING SURFACES OF THE BEARING PAD AND SAID OTHER MEMBER SUCH THAT WHEN OIL UNDER PRESSURE IS DIRECTED INTO SAID FLUID POCKET IT IS PERMITTED TO DRAIN THEREFROM THROUGH SAID CLEARANCE GAP AND THEREBY PROVIDE A UNIFORM FILM OF OIL BETWEEN SAID LAST TWO MENTIONED BEARING SURFACES.

Claim 2

THE METHOD OF FORMING A HYDROSTATIC BEARING ASSEMBLY ADAPTED FOR SUPPORTING A MOVABLE MEMBER FOR HIGHLY ACCURATE MOVEMENT WITH RESPECT TO A BEARING SURFACE OF A SUPPORT MEMBER, SAID ASSEMBLY INCLUDING A BEARING PAD ON ONE OF SAID MEMBERS HAVING A FLUID POCKET IN ONE FACE THEREOF WHICH IS PERIPHERALLY SURROUNDED BY A BEARING SURFACE JUXTAPOSED AND CLOSELY CONFORMING IN CONTOUR TO A BEARING SURFACE OF THE OTHER MEMBER, SAID METHOD COMPRISING THE STEPS OF FORMING A RECESS IN ONE OF SAID MEMBERS WHICH IS ADAPTED TO RECEIVE THE BEARING PAD WITH A RELATIVELY LOOSE FIT, INSERTING THE BEARING PAD WITHIN SAID RECESS AND ASSEMBLING THE MOVABLE MEMBER WITH THE SUPPORT MEMBER SO THAT THE BEARING SURFACE ON THE BEARING PAD IS ACCURATELY ALIGNED AND IN BEARING CONTACT WITH THE BEARING SURFACE ON SAID OTHER MEMBER, FILLING THE PORTION OF THE RECESS NOT OCCUPIED BY THE BEARING PAD WITH A RESINOUS MATERIAL WHICH WHEN SET IS ADAPTED TO RIGIDLY BOND THE BEARING PAD TO SAID ONE MEMBER AND LOCATE THE BEARING PAD IN RIGIDLY FIXED POSITION ON SAID ONE MEMBER IN ALIGNMENT AND BEARING CONTACT WITH THE BEARING SURFACE ON THE OTHER MEMBER, CAUSING SAID RESIN TO SET, AND THEREAFTER FORMING A CLEARANCE GAP OF UNIFORM WIDTH BETWEEN THE BEARING SURFACES OF THE BEARING PAD AND SAID OTHER MEMBER SUCH THAT WHEN OIL UNDER PRESSURE IS DIRECTED INTO SAID FLUID POCKET IT IS PERMITTED TO DRAIN THEREFROM THROUGH SAID CLEARANCE GAP AND THEREBY PROVIDE A UNIFORM FILM OF OIL BETWEEN SAID LAST TWO MENTIONED BEARING SURFACES.
